Automotive-grade audio amplifier and sensors for intelligent cockpit systems

NOVOSENSE Microelectronics debuts its NSDA6934-Q1 Class D audio amplifier and the NSHT30-Q1 temperature and humidity sensor.

The NSDA6934-Q1 is a high-efficiency, four-channel Class D amplifier with digital input, delivering up to 75W per channel. Specifically optimised for external power amplifier application, it manages key automotive audio challenges by dramatically decreasing audio path latency by over 70% via its unique low-latency mode. This allows more processing time for DSP-based features such as Road Noise Cancellation (RNC) while decreasing computational load.

With support for up to 192kHz sampling rates and multiple modulation modes, including BD and 1SPW, the amplifier adapts to high-output and low-power scenarios, making it highly flexible for compact, space-constrained cabin designs.

The device is also highly configurable and supports adjustable switching frequencies from 384kHz to 2.1MHz, permitting engineers to optimise for efficiency and size constraints. The amplifier includes multiple EMC optimisation techniques through spread-spectrum techniques, slew rate and phase control, enabling easier compliance with automotive EMC standards.

Complementing the audio system is the NSHT30-Q1, a highly integrated temperature and humidity sensor that plays a vital role in environmental sensing for improved passenger comfort and system reliability. With digital I2C output and automotive-grade resilience, the device helps maintain climate control precision within the increasingly sensor-dense architecture of intelligent defogging and vehicle cabins.

By combining powerful signal processing components with compact form factors and robust protection mechanisms, the company's smart cockpit solutions provide engineers a practical pathway to support the shift toward software-defined, sensor-rich vehicle platforms.
